Setting the Range, Resolution and Averaging
This section provides an overview of setting the range, resolution and
averaging. For more detailed information about these features refer to the
individual commands in Chapter 9.
Range
The power meter has no internal ranges which can be set. The only ranges
that can be set are those of the HP E-series power sensors. With an
HP E-series power sensor the range can be set either automatically or
manually. Use autoranging when you are not sure of the power level you
will be measuring.
Setting the Range
To set the range manually use the following command:
[SENSe[1]]|SENSe2:POWer:AC:RANGe <numeric_value>
If the <numeric_value> is set to:
• 0, the sensor’s lower range is selected. (For example, this range is
-70 to -13.5 dBm for the HP ECP-18A power sensor.)
• 1, the sensor’s upper range is selected. (For example, this range is
-14.5 to +20 dBm for the HP ECP-18A power sensor.)
For details on the range limits of other HP E-series power sensors refer to
the appropriate power sensor manual.
For further information on this command refer to page 9-51.
To enable autoranging use the following command:
[SENSe[1]]|SENSe2:POWer:AC:RANGe:AUTO ON
Use autoranging when you are not sure of the power level you will be
measuring.
